在Linux上将libc ++链接到CMake项目 [英] Linking libc++ to CMake project on Linux

问题描述

我想在CMake项目的Arch Linux上将libc ++和clang一起使用.我安装了libc ++，并按照 LLVM站点的Linux部分在Linux中使用libc ++您的程序":

I want to use libc++ together with clang on Arch Linux in CMake project. I installed libc++ and added following lines to CMakeLists.txt as said on LLVM site in Linux section of "Using libc++ in your programs":

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -stdlib=libc++")
set(CMAKE_EXE_LINKER_FLAGS "-lc++abi")

我在链接器的标志中仅尝试了"++ abi"，但这没有帮助.我需要一些帮助来确定我应该在CMakeLists.txt中写些什么.

I have tried just "++abi" in linker's flags, but it didn't help. I need some help in figuring out what i should write in my CMakeLists.txt.

推荐答案

别忘了将编译器设置为clang ++:

Don't forget to set the compiler to clang++:

set(CMAKE_CXX_COMPILER "clang++")

此外，清除cmake生成的文件(删除文件夹CMakeFiles和CMakeCache.txt).

Also, purge the cmake generated files (delete the folder CMakeFiles and CMakeCache.txt).

根据您的系统，它可能也有助于设置

Depending on your system, it might also help to set

set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -stdlib=libc++ -lc++abi")
